A circular coil of 1000 turns each with area 1 m ^ 2 is rotated...

Given, $N = 1000, A = 1{m}^{2}$and $B = 0 . 07T$

The maximum emf generated is {ε}_\max = NBA\omega,

$= NBA\left(2\pif\right)$

$= 1000 \times 0 . 07 \times 1 \times 2\pi\left(1\right)$= 140\pi$</p><p>Thus, maximum emf is$439 . 6V \approx 440V$.
